Title: Cancelling characteristics assigned to subscribers - using recognition of special characteristic from subscriber to computer whether cancellation is valid
Inventor: KRETZ HANS-JOACHIM
IPC: H04Q3/62
Filed: 1980-08-06
Abstract: The cancelling system consists of a process store in which a storage cell - consisting of several store-words - is provided for each connection. The store-words are individually addressable and the dialled or special characteristic given by a subscriber is first received by a selector unit on the line, or in the case of dial switch selection of a preprocessing unit, directly read. If the characteristic consists of more than one figure, it is transmitted individually to a central control unit to be entered in the storage cell allocated to the subscriber in the process store. If the characteristic is complete, the central computer calls the cancelling program from its store. After addressing a store word (SPW), the contents are taken into a process register where the computer tests whether the relevant characteristic is given by the subscriber and whether it may be cancelled. The subscriber hears either an 'occuPied' or 'free' tone, depending on whether the characteristics may or may not be cancelled by the subscriber.

Patent DE-3107604-A1 (DE)
Title: Arrangement for rail contacts which can be influenced inductively
Inventor: SCHMIDT HARALD DIPL ING
IPC: B61L1/08
Filed: 1981-02-27
Abstract: In the case of inductive rail contacts there is the problem that the receiving devices of this equipment can be so strongly influenced by the traction current flowing in the rails that their functional capability is not always ensured. Thus, in addition to high-frequency influencing, in particular by contact line circuits, low-frequency influencing of the track equipment by means of traction currents also takes place. In this case, the traction currents magnetise the rail material periodically and thus bring about a change in the permeability of the rails. Since a large portion of the magnetic field lines which originate from the transmitting devices of a rail contact and influence the receiving devices is conducted in the rails, consequently a periodic change in the voltages induced in the receiving devices of the rail contact takes place, which change can simulate response of the rail contact and, however, at least leads to a reduction in the response sensitivity. The invention provides for a layer (5) which is made of material with poor magnetic conductivity and fits tightly against the travel rail to be arranged between travel rail (1) and receiving device (31, 32) which layer (5) covers the travel rail from the underside of the rail head to the outer edge of the rail foot. As a result of the formation of eddy current, this layer leads to an extensive field displacement that is to say the influencing of the rail contact being reduced when the track is clear. Thus, the influence of the traction current on the receiving device is also reduced. The voltage induced in the receiving device does not suddenly jump to a value which is sufficient for triggering a reaction until the rail contact is travelled over.

Title: Device for heat treatment of scrap
Inventor: BOUILLE BERNARD
IPC: C21C5/56
Filed: 1981-05-25
Abstract: A device for heat treatment of scrap with a charging device which guides the scrap to a furnace space with a smoke-gas offtake and charging opening and is if appropriate designed as a carriage and in the storage space of which the scrap is subjected to a preheating process, is to be improved in such a manner that on the one hand it is easy to handle and on the other hand it can be operated with relatively low energy loss. This is achieved by the storage space of the charging device being connected detachably to the furnace space and/or smoke-gas offtake and fed with waste heat from the furnace space, that storage space preferably being part of a smoke-gas or waste-heat circuit. Within the scope of the invention, the storage space is additionally provided with a length-adjustable discharge - if appropriate of telescopic design - and the latter can be pushed into the charging opening.

Title: Process for sharpening cutters for cutter heads for machining wood and plastics, cutter sharpened by the process and cutter head with cutters of this type
Inventor: BRUCKLACHER DIETER DR ING
IPC: B24B3/08
Filed: 1981-05-26
Abstract: In a process for sharpening cutters for cutter heads for machining wood and plastics, the invention provides that, during grinding of the cutter profile which is carried out using a grinding template, at least one stop nose, serving to position the cutter in the associated cutter head, is also ground, as constituent part of the cutter profile, with the aid of the same grinding template. The mutual positioning, which is fixed once on the grinding template, between stop nose and the remainder of the cutter profile provided for machining is thus maintained in an unchanged state in all sharpening procedures, with the result that the size of the cutting-edge orbit of the cutter remains unchanged even after re-sharpening. A cutter sharpened by the process has, as constituent parts of its cutter profile, in addition to at least one main cutting edge which is used for workpiece machining, at least one adjustment cutting edge, as stop nose, which forms with its cutting edge a reference line for the adjustment of the cutting edge orbit in conjunction with a stop on the associated cutter head. A cutter head provided for the use of such cutters has, as stops, stop surfaces for the adjustment cutting edges of the cutters.
